Hybrid single nanoreactor for in situ SERS monitoring of plasmon-driven and small Au nanoparticles catalyzed reactions†
Abstract
A hybrid single nanoreactor composed of small Au nanoparticles (NPs) and a long Ag nanowire (NW) with a length of 10 μm can be conveniently located by optical microscopy, allowing us to monitor by in situ surface enhanced Raman spectroscopy (SERS) the plasmon-driven and small Au NPs catalyzed reactions with high sensitivity and reproducibility.
